OK, I have been fighting with my 1981 300TD blower motor. I thought I "temporarily" fixed it about a month ago, but now it is not coming on at all.
Here is the scoop:
The heater works...but the BLOWER works only erradically. Does not work to jiggle the key, bang on lower dash panel by motor, etc. I think I have to actually repair something.
Once in a GREAT while, we will be driving and the blower will come on. For a second. I mean a second. THen it shuts back off.
First question: does the blower only come on when the A/C compressor is running? Strange, but that seems to be the only time it will kick on.
Next question: If the A/C compressor was going bad, would that affect the blower?? (I don't think it should...)
I have checked the pushbutton controls, and they are apparently OK, as it works just fine when the blower is actually on, and the blower motor/brushes seem fine too.
It is VERY cold now and my wife will not drive it until I get it fixed.
ANY SUGGESTIONS??
Thanks in advance!
